image - Alt Tags not working on my site -

-

i trying figure out why alt image tags not working on site www.slickcar.com. have reviewed alt= tag , looks correct when @ in ie, chrome or firefox not display when hover on images.

the alt attribute not meant tooltip. serves text alternative image, e.g. screen reader or text browser users, search engines etc. value of alt attribute should describe content (= image), can understand meaning/purpose of image without seeing it.

the value of title attribute typically shown tooltip. should give additional (and not alternative) information.
